Electronic leak detection in St Cross
Our ELD report shows where each breach was found, with photos. It tells your roofer exactly where to repair rather than guessing. We do not estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We are often asked to look into leaks that return after repairs and leaking laps in the waterproofing, across roof terraces and balconies, single-ply roofs and green roofs.
Outbuildings, garden rooms and garages in places like St Cross often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It’s worth mentioning them when booking, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to.

Tips that help
There is plenty you can do without going near the roof. What helps most:
- Do not leave water getting in
- Note where leaks show inside and when
- Ask contractors to protect the membrane
- Keep foot traffic on flat roofs to a minimum
Keep the report with the roof’s records. It’s a dated record of the membrane’s condition.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
What we do, step by step
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. A visit to St Cross is planned like any other: the time, the access and where to park are agreed ahead of time. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Leave a clear route to the loft
- Jot down any questions you want answered
- Note where any stains or damp appear

Electronic leak detection around St Cross
St Cross has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent.
The streets around a church like St. Cross Church are often among the oldest in a place, and if your home is one of the older ones nearby, the joins between later flat roofs and the old walls are where problems normally start. A roof leak in a hotel or guest house around St Cross means lost rooms as well as repairs.

A survey is a careful look at the flat roof membrane, but it cannot do everything. Its limits include:
- Repairing the breaches (that is for your roofer)

St Cross: your questions answered
Does a conservation area affect roof work in St Cross?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is St Cross within the area you cover?
Yes. St Cross is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Just mention lanes, gates or anything else about the route as you book.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How fast do I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us as you book.
Does ELD include fixing the breach?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
How long will testing take?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
Is my roof suitable for ELD?
ELD does not suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we’ll say so at the start.
What we’re asked to look at in St Cross
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
These are some of the problems a survey can pick up:
- Holes around roof penetrations
- New membranes needing a check before handover
- Patched roofs that still leak
- Leaks under green or ballasted roofs
If you own a rental within reach of Winchester station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Questions to ask before you book
- What they won’t be able to tell you
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Their drone registration, if they fly one
- Whether the roof space is looked at, where there is one
For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photographs included.
Letting agents often book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant beforehand.
